In a study of young adults in Greece (aged 21–50, mean age 40.9 years), the prevalence was found to be 7.35%. [4] While among urologic patients in South Korea (aged 29–89, mean age 61.9 years), the prevalence was 40.7%. [5] The prevalence is notably higher in patients with benign prostatic hyperplasia, ranging from 68.8% to 70%. [3]
The International Prostate Symptom Score (IPSS) can be used to gauge the symptoms, along with physician examination. Other primary and secondary tests are often carried out, such as a PSA (Prostate-specific antigen) test, [17] urinalysis, ultrasound, urinary flow studies, imaging, temporary prostatic stent placement, prostate biopsy and/or ...
The prostate gets larger in most men as they get older. For a symptom-free man of 46 years, the risk of developing BPH over the next 30 years is 45%. Incidence rates increase from 3 cases per 1000 man-years at age 45–49 years, to 38 cases per 1000 man-years by the age of 75–79 years.
Ultrasound involves a probe that is placed near a structure and uses the transmission of ultrasound waves through a structure to produce images, after computer processing. [1] Ultrasound of the urinary tract is performed by a probe placed on the abdominal wall, called a transducer. [1] This occurs while a person is lying down. [1]
Transrectal ultrasonography, or TRUS in short, is a method of creating an image of organs in the pelvis, most commonly used to perform an ultrasound-guided needle biopsy evaluation of the prostate gland in men with elevated prostate-specific antigen or prostatic nodules on digital rectal exam.
If the prostate grows too large, it may constrict the urethra and impede the flow of urine, making urination painful and difficult, or in extreme cases completely impossible, causing urinary retention. [28] Over time, chronic retention may cause the bladder to become larger and cause a backflow of urine into the kidneys (hydronephrosis). [28]
